Neozeed et al managed to access graphic video modes under xenix, and quickly built an appropriate doom port...
...so I altered and extended the Xenix286 from-scratch-VM autoinstaller script, which contains the following stuff at the moment:
- Xenix386 v2.3.4 (for 80386 or newer cpu)
- Games package
- Tetris for 286
- (fake) Mouse setup triggered during install (doom build's requirement)
- Doom binary package (total 5 floppies)
- md5 checksums of all floppy images provided
- hard disk with C/H/S geometry 900/15/17
The resulting Xenix386 hard disk image is a real retrogamer heaven incl. tetris, backgammon, robots, and last but not least: doom! :)
Default credentials are root/xenix386 for username/password. "/usr/games" folder is in the PATH variable, so simply type doom command after login in order to launch your favourite one-player gauntlet!
